FUNCTIONALIZED LIGHT FILTER FOR SWIR OR VIS-SWIR DETECTOR, AND USES THEREOF

摘要

The invention relates to an optical device comprising at least one detection layer comprising at least two detectors (21, 22, 23) capable of detecting light signals located at least in the infrared at short wavelengths, and a transparent material (4) for the light detected by the detectors and functionalized to filter the light or to modify the polarization state of the light arriving at the detection material, the functionalized material being provided with at least one zone functionalized by nanostructures (41, 42, 43, 44) and a remaining area of the functionalized material, the nanostructures being located in the volume of the functionalized material, said at least one functionalized area and said remaining area being located in correspondence respectively with the at least two detectors of the detection material. .
